PATENT GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 555,141, dated February 25,1896.

Application filed September 3,1895. SerislNO. 561,382. (No model.)

To all whom it may cancer-mu.

Be it known that I, Euonivn lli. Wnsoort, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas-Burners; and I do declare thefollowing to be afull, clear,and exact description of the invention, such'as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and the letters of reference-marked thereon, which form a part of this specification.

The invention relates more particularly to the application of the Bunsen burner to gaslamps; especially of the class known as the lVelsbach incandescent gas-lamp, in which the flame is located'within a non-combustible mantle which is rendered incandescent.

The object of the invention is to adapt such burner for the use of hydrocarbon gas,as well as toincreaseits efiiciency when gas of greater buoyancy is used.

The invention consists in forming the mixing-chamber in the upper end of the Bunsen tube so that it is not necessary to raise a heavy gas anyconsiderable distance after it is freed from the direct pressure within the service-pipes. i

Itconsists further in a peculiar form of regulating-valve for controlling .the delivery.

of the gas into the mixing-chamber of the Bunsen tube, whereby the advantageis secured of discharging the gas in a number of fine jets, and consequently with very considerable velocity,the discharge-apertures being of such form that their area may be varied i cis located within "the tube (J immediately below the ports 0 and is centrally apertured. The 'lower'endof the tube 0 is externally at pleasure.

It consists further of means for varying the air-supply as the flow of gas is varied,v

In illustrating my invention I show in Fig-. ure 1 an elevation of the burner complete and" ready'for use; Fig. 2, a central vertical section on the line 2 2 of Fig. 1; Fig. 3, a plan section on the line 3 3 of Fig. 2; Fig. 4, a plan section on the line 4 4- of Fig. 2; Fig. 5, a detail of the burner, partly in section; Fig. 6, a detail of the governing-valve.

In burners of this character it is necessary.

that the gas be discharged into the mixingchamber with considerable velocity to produce the necessary suction to draw in the air.

form therewith a gas-tight joint.

In order to secure this velocity it has been the practice to introduce the gas in one or more jets, using a tube with a closed end and puncturing the end to admit the. required quantity of gas. found to be too small more was secured either byincreasing the size or number of the holes.

If the quantity proved to be too great it was reduced by plugging one ormore of the holes or reducing their area.

- In my improved burnerl secure the requisite velocity and provide means for complete control of the quantity of gas bythe- .use of a plug-valve havingports in the form of grooves running back from itsend and diminishing in area until they run to the surface. A By withdrawing this valve from its seat these ports are gradually opened.

It has been found impracticable'to use hydrocarbon gas in a burner of this kind except under great pressure, for the reason that this gas is too heavy to rise in the tube and must be forced out. By placing the mixing-chamher in the upper end of the tube'I avoid forming this long column of free gas and throw the jets beyond the mouth of the tube.

If the quantity of gas was c The outer frame of my burner may be of I "the air being conducted to these ports by a tubular casing E extending downwardly and open at its lower end. A transverse partition carries a stemd projecting beyond the upper end of the nipple and adapted to enter the aperture in the partition 0 in the tube 0 and The stem cl is of less diameter than the interior of the tube 1), and around it the partition'd' is per too forated, as indicated at (1 for the free pas- "sage of the gas; A plurality of small grooves are out 1n the sides of the stem (1, starting from its upper end and taperingdownwardly until they runout or disappear.

By this means both-the ainand gas supply can be regulated by simply turning the burner around.
